This invention relates to wheels, more particularly band-saw-wheels, and'has forione ofits objects to provide asimply constructed 1 device of this character which is strong and 5 durable, inexpensive -to manufacture, and adaptedfor' use Wherever a band pulley is required. w I

F or the purpose of illustration the improved pulley is shownjappliedto a band p 1 0 saw device, to which it is more particularly adapted, but itwill be understood that it is not desired to limit thefinvention for use in connection with any specific machine or ap- 7 as shown.

paratus. V V L I r In the drawings illustrative of the applica- "tion of the invention I V f Figure; 1 is aside elevation of a conventional band saw with a pair of the improved pulleys mounted therein. v Figure 2 is an enlargedsectional detail of one of the improve d'pulleys.

V Theimproved pulley includes a'hub member comprising a body 10' longitudinally bored to engage the journal of a shaft 11;

' and with annular flanges 12and 13 in spaced relati.on,"oneof the flanges, for instance the flange 18, being detachable and slidableon the hub :as indicated in Figure2 and constituting a movable clamping member. The rim of the wheelis in two annular portions 14 and 15, and disposedbetween the rim portions are theouter parts of disk v v p "hub, an annulus interposed betweensaiddisks at thenner marginal portions thereof membersjldand 17. An endless band meinber 18, preferablyofrubber 'or the like, bears around the outer faces of the rim secmembers, as'shown; 1 v a V The disks l6 and 17 are diverged toward the hub and bear respectively against the Disposed between-the flange'12 and the "annular clamp member 13, is; an annular spacer member '19, the jfiange, clamp anemb'er,'dislzs and spacer'member" being secured inposition, by transverse clamp bolts 2O. 1

The annular member 19 is considerably greater in interior diameter than the body 10 of the hub, whereby anannularchamber scope oif the claimed invention maybe made n the construction; without departing from" .bricanttrapping chamber having said'ports 4. communicating therewith,.sai'dannulus r0 viding spacing means between the v fl the inner marginal portions ther-eonjhold I confronting fac-esofthe flanges 12 and 13." fast devices for securingsaid flangesfdisks' 21 is provided between the-'hub-lm fianges 12 and 13 and the spacer member 19,;0 cone, I ftain a supply of alubricant which passes' I by .oil orifices 22-to the journal of'the wheel. ,An. oil inlet," indicated at; 23, provides.
